To all 'whom it may concern Be it known that I, Ti-ioMAs Davis, a subject of the King of at Vancouver, in the Province of British Columbia and Dominion of Canada, have invented certain new 'and useful Improve ments in Cross-Ties, of which the following is a specification.-

This invention relates to improvements in railway ties and has for its object to provide a combined sleeper and rail chair structure designed to be formed of metal and constructed and arranged to insure anchorage of the rails, not only to their proper-gage, but to also prevent spreading of the rails.

One of the special features of my invention resides in structural features whereby any movement of the rails from their gaged position will be resisted by locked metallic structural parts.

A further feature of the improvement consists in the novel construction whereby removal and replacement of the rails may be readily effected.

'Ihe invention includes other features of novelty and construction which will be more fully described iii connection with the accompanying drawings and which will be more particularly pointed out in and by the appended claims.

In the drawings z-Figure 1 is a cross sectional view of two rails mounted upon and secured to one form of the device of my invention. Fig. 2is a plan view of the structure shown in Fig. 1. Fig. 3 is a sectional view on line 3-3 of Fig. 1. Fig. 4 is a sectional view Von line 4 4 of Fig. 1. Fig. 5 is a longitudinally vertical sectional view of one end portion of my improved sleeper.

Fig. 6 is a perspective view of one of the movable i'ail shoes.

Like characters of reference designate l similar parts throughout the dierent figures of the drawings.

Referring to the form illustrated, 1 designates a sleeper which is designed to be formed of metal and which is of channeled cross section having outwardly extending ianges 2. While I prefer that the sleeper, like the Vremainder of the structure, should be made of metal, it will be understood that the sleeper may be formed of concrete or other suitable material if desired.

Chairs for the rails are shown consisting of a single piece of material which may be in the form of a flat plate 3 adapted to be Great Britain, residing bolted or otherwise secured to the flanges 2, and shown extending throughout the length ofthe sleeper 1. The chair plate 3 is provided with preferably integrally formed shoes 4 adapted for engagement with the outer faces of the rail webs and flanges. The rails which are designated at 5, rest upon the chair plate 3 as shown in Fig. 1, and I provide movably mounted shoes 6 and 7 for engaging the inner` sides of the rail flanges and webs. The inner shoes 6 and 7 are slid ably mounted upon the chair plate 3, and as illustrated in Fig. 4, the chair plate 3 is provided Vwith a depressed and preferably dovetail grooved top portion 8, which extends inwardly toward the longitudinal center of the structure for a relatively considerable distance.. As shown, said dove-tail grooved top portions 8 terminate in an enlarged portion 9, as clearly shown in Fig. 2. The shoes 6 and 7 are provided with dove-tailed projections 10 and 11 adapted to fit the dovetailed grooves of the rail plate 3. The central enlargement 9 is of sufficient size to permit of withdrawal or insertion of the base extension 10 or 11 of either of the shoes 6 or 7 so as to position the shoes in a manner to permit of their being moved upwardly from the enlargement 9, into engagement with the f rails 5, as shown in Fig. 2.

It will be seen that the dove-tailed fit of the shoes 6 and 7 with the chair plate 3, serves most effectively to lock the shoes, by means of rigidly structural parts, against upward displacement so that the said slices will be capable of successfully resisting upward movement of the rails which may take place from contraction or following the release of the load as a train advances.

In order to provide for locking action of the shoes 6 and 7 against movement inwardly ofthe rails, I provide rigid means which may be in the form of a bar 12. The shoes 6 and 7 are provided with recesses 13 and 14 adapted to receive the ends of the bar 12, and also the shoes 6 and 7, are suitably apertured to receive bolts 15 and 16. Thus when the bar 12 is in position, as shown in Figs. 1 and 2, the shoes 6 and 7 will be rigidly locked against the inner sides of the rails 5, and the latter will be securely seated against the outer shoes 4.

While I have shown outer shoes having flange-engaging portions 17 and inner shoes having flange-engaging portions 18 and 19,

each also having a rail web-engaging pora chair plate 3, wh

chair plate will serve for one of the novel features consists m a chair plate having a rigid shoe VClapiers of this patent may be obtained for tion, I may in some constructions omit," the especially at such web-engaging portions, u points where the track is Straight and where the tendency to spread the rails is less prO nounced than on curved portions of the track. In Fig. 5, the web-engaging portion of the shoe'll is indicated at 20, and in Fig. 6, the web-engaging portion of shoe V@is indicated at 21.

It will thus be seen that I have provided ich may, as shown, extend completely lengthwise ofthe `tie so that one A both rails, and in this connection, I desire to assert that irrespective of the character of the sleeper used, of the invention for engagement with one side of a rail and an adjustable shoe for engagement with the other side of such rail. l

VWhile I have herein shown and described one specic embodiment of my invention, I do not wish to be limited thereto, except'for such limitations as the claims may import. Iclai'm:- 1 v l.
